ACCA may refer to:
Acca of Hexham (c. 660 – 740/742) was a Northumbrian saint and Bishop of Hexham from 709 until 732.
Born in Northumbria, Acca first served in the household of Bosa, the future Bishop of York, but later attached himself to Saint Wilfrid, possibly as early as 678, and accompanied him on his travels. Later he told his friend Bede of their stay at Utrecht with the saintly Archbishop Willibrord, Wilfrid's old pupil who was carrying on his work of converting continental heathens. On the return from their second journey to Rome in 692, Wilfrid was reinstated at Hexham and made Acca abbot of St Andrew's monastery there. During St Wilfrid's later years, Acca was the older man's loyal companion, eventually succeeding him in 709 as abbot and bishop.
Acca tackled his duties with much energy, in ruling the diocese and in conducting the services of the church. He also carried on the work of church building and decorating started by Wilfrid. Acca was both an accomplished musician and a learned theologian. He once brought to the North a famous cantor named Maban, who had learned in Kent the Roman traditions of psalmody handed down from Gregory the Great through Saint Augustine.
Acca (formerly Feijoa) is a genus of shrubs and small trees in the Myrtaceae family, first described as a genus in 1856.
It is native to South America.
Acca sellowiana is cultivated for its edible fruits, known as feijoas or pineapple guavas.
